What were the difficulties?

It take me 2 days . To retro-fit the IHKR with the IHKA you need to take out the front interior ( this was a difficulty ) , the ventilation pipes . Then you need to unscrew 5 screws and voila the old IHKR is free then you need to pull her out and to replace it with the IHKA
